When I worked in the hospital, I certainly found this to be true. While I was priveleged to care for many nice, respectful people, a significant proportion of patients and their family members arrived at the hospital with an adversarial attidude already in place. Sometimes, by using my charms, I could change the dynamic, but not always.
I am more than willing to cut people slack for not being at their best because they are scared, in pain, or just not feeling well. But for some people, they just function at a baseline of entitlement and disrespect regardless of the circumstances, and I have no tolerance for that.
Now that I work in an outpatient capacity, my experience is completely different. I have found most people are happy to see me, do not ask me to do things outside of my role, and are respectful of the knowledge and skills I possess. I am much happier as a nurse in this capacity.
Sometimes when I consider going back to the hospital, this is definitely an issue that comes into play.
